CHA6105
RoHS COMPLIANT
8-12GHz Driver Amplifier
GaAs Monolithic Microwave IC
Description
VD1
The CHA6105 is a monolithic three-stage
medium power amplifier designed for
X-band applications.
The driver provides typically 31.5dBm
output power at saturation and is suitable
for systems requiring a high compression
level. Moreover it includes a biasing
control circuit that makes Pout less
sensitive to spread and chip environment.
